Azure-docs: Microsoft Form Recognizer to process form image URL download

[vionemc]

I succeed to use the Microsoft Form Recognizer using the sample from the quick start.

https://docs.microsoft.com/en-us/azure/cognitive-services/form-recognizer/quickstarts/python-receipts#feedback

But what I have now is image URLs which trigger download instead of opening a raw image in the browser. How can I be able to handle that?

@vionemc Thanks for the question! We're investigating this and will get back to you shortly.

[vionemc]

Thank you for the response! It has been hard for me to use this tool without some flexibility to handle multiple cases

[vionemc]

How about handling the raw image directly? I can give you the file type

@vionemc Form Recognizer works on input that meets below requirements.

@vionemc please add your use case details that you are trying to solve.

[vionemc]

@vrishni for example, I am trying to process this URL https://justanalytics.harvestapp.com/expenses/25592242/receipt

It triggers a download and gives the raw image body as a response when I scrape it.

If you can accept raw image body instead of a hosted URL, I can work on it

Form Recognizer custom Analyze API supports as input a local file or multi-part form it does not yet support a URL. The Form Recognizer Analyze Receipt API supports also a URL as input format.

For anyone out there who needs a solution for this, I found this in the documentation. You can handle it by passing the binary of the image file, but you'd need a different header.

########### Python 2.7 #############
import httplib, urllib, base64

headers = {
    # Request headers
    'Content-Type': 'application/octet-stream',
    'Ocp-Apim-Subscription-Key': '{subscription key}',
}
body = {Your binary data}
params = urllib.urlencode({
})

try:
    conn = httplib.HTTPSConnection('westus2.api.cognitive.microsoft.com')
    conn.request("POST", "/formrecognizer/v1.0-preview/prebuilt/receipt/asyncBatchAnalyze?%s" % params, "{body}", headers)
    response = conn.getresponse()
    data = response.read()
    print(data)
    conn.close()
except Exception as e:
    print("[Errno {0}] {1}".format(e.errno, e.strerror))
